Air conditioning for extensions and kitchen-diners in Gravesend
In Gravesend, a side wall of a single-storey extension is usually the neatest place for the indoor unit. Summers in the South East are among the warmest in the country, so cooling often comes first, with efficient winter heating as a bonus.
An extension in Gravesend with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. Our Kent coverage takes in Gravesend, about 14 miles from Maidstone. Homes in DA12 are all within our coverage.
Prices in Gravesend
Our South East England guide price for air conditioning for extensions and kitchen-diners is £1,745–£5,445 per space, VAT included. Prices here sit above the national middle, reflecting South East England labour rates and parking and access costs. The biggest variables are the pipe route, access for the outdoor unit and the state of the consumer unit, all of which the survey settles. As an example, the Large single option (one 5–7 kW unit for a large glazed space) would typically be £2,495–£3,495 here.
Single unit
One 3.5–5 kW unit for a medium extension.
Large single
One 5–7 kW unit for a large glazed space.
Twin units
Two indoor units on a multi-split for long or L-shaped spaces.
Guide prices show VAT at 20%. HMRC treats most fixed air conditioners and air-to-air heat pumps installed in homes as energy-saving materials, zero-rated until 31 March 2027 when we supply and fit them. If your installation qualifies, your quote shows 0% VAT and a lower price. Servicing, repairs, cleaning and controls are charged at 20%.
Planning and permissions
England's rules let most houses fit an outdoor unit without a planning application, as long as the size, number and MCS 020(a) noise conditions are met. Flats, listed buildings and roof-mounted units are treated differently.
The survey

A survey in Gravesend usually takes one to two hours. We measure the rooms, check the walls and the consumer unit, agree the outdoor unit position with you and photograph the pipe routes.
